Scroll down to the section entitled "Should we be worried about the Oxford AstraZeneca vaccine?"
In short, quote:
"Are UK scientists worried?
No. The overwhelming scientific opinion is that there is no certain link between blood clots and the vaccine, and the reported cases could easily be coincidental."
"What has AstraZeneca said?
The pharmaceutical firm said a 'careful review of all available safety data' of more than 17 million people vaccinated in the EU and UK with the AstraZeneca jab has shown 'no evidence of an increased risk of pulmonary embolism, deep vein thrombosis (DVT) or thrombocytopenia, in any defined age group, gender, batch or in any particular country'.
Its chief medical officer Dr Ann Taylor said the number of cases of blood clots reported in this group 'is lower than the hundreds of cases that would be expected among the general population'."
